1  Discussion Boards / Williams by Bachmann / Re: Locking GP525 Burlington GP9 in Forward on: November 15, 2016, 06:38:56 PM
I purchased the bridge rectifier and installed it, which was easy to do.  Engine is now locked in forward.  Thanks for your help.

Hello.  I'm new to your board, and I have a question? 

We purchased a vintage Williams engine identified on the box as "GP525 Burlington GP9 Power A W/Horn CAB # 2329".  This engine was purchased for use in a children's museum where I do volunteer work.  It's essential that we lock the engine in forward.

I have modified a few Rev. 4 circuit boards to lock the engine in forward, but, even though one of the boards in this engine looks very much like a Rev. 4 board, the same mod doesn't do anything.   The board is identified as a 247 Category 1 reversing board, Patent # 5,321,344, and 335-X001R2.  This appears to be an engine from the early 1990's when locking into a direction may not have even been discussed.

Would anyone know if this engine can in fact be modified to lock it into forward?

Thanks for any help.
